John Stapp performed rocket sled experiments in the late 1940's and early 1950's and survived a 46 G decleration. He died at age 89 in 1999.

When you say g forces, people think of fighter pilots, but they are not what I think of when you say "average human". They are physically fit and trained to tolerate excessive and prolonged g forces. On their "average", around 7.5 to maybe even 9 at times is tolerable. Also, it is usually the duration of the forces, not just the intensity.
For the average person I would venture no more than 3,4 max. This is why even though some roller coasters may seem really really cool, they generally do not ever generate more than 2 g's so "average" people can ride them--or, if they do produce more, the force occurs only for mere instants. Otherwise, if they designed in longer and higher g turns, only fighter pilots would ride them.

Some can handle ultra brief g force levels of well over 30 g (e.g, in some of the 'sled tests' carried out in the USA and the UK). Aspiring F16 (I think) US pilots had to (perhaps one will write in to confirm) take up to 10 g on pre assessment. Most fighter pilots will regularly experience 6 or 7 g during training exercises. I've experienced around 6 g in a two seater fighter trainer and it was weird... beginning of tunnel vision and a feeling of having a ridiculously heavy pair of arms! It gave me great respect for modern fighter pilots who not only have to fly the aircraft, but use them as a weapons platform too! No wonder they have to meet strict medical requirements... and no wonder many eventually get haemorrhoids!

according to NASA 9 w/o passing out and a g-suit. it was sustained for 30 secs
and according to wikipedia..
Colonel John Stapp in 1954 sustained 46.2 g in a rocket sled, while conducting research on the effects of human deceleration

G Force:The acceleration due to gravity on the Earth's surface at sea level is equivalent to 1 g (pronounced gee) which is a non-SI unit of acceleration defined as exactly 9.80665 m/s2 (almost exactly 32.174 ft/s2); g-force or g-load is a force-equivalent, equal to 9.80665 N/kg.

I think impact during car accidents may go upward to 14 or higher. It'll mess you up inside, but survivable.

9 g. is the usual, more than that, humans will have severe wounds, and body disintegration.

ON THE AVERAGE 8, YOU DIE AT 12
